ADJUSTABLE JGENT.

To aZZ whom it may concern:

Be it known that T, WILLIAM Hanna BovAnn, a citizen of the UnitedStates, and

pending application, Serial No. 5655M, the 15 improvement consisting ina more perfect locking engagement between the members to be joined.

The frame ofa motor vehicle usually curves downward where 'it engagesthe '20 vehicle spring, and these curves vary with the different makesof motor vehicles. The frames also vary in cross'section and it is oneof the objects of the present invention to rovidea suitable jolntbetween the 2s brac et holding the bumper and the frame member that maybe used. for practically any motor vehicle and may be easllyad usted sowas to maintain the bumper in-its proper-position.

With these objects in view ll have shown the preferred form of myinvention in-the accompanying drawing in which Figure 1' shows a sideelevation of m device secured .to the frame of an automo ile, Figure 2 ato lan view of the same, Figure 3 a vertical ongitudinal section throughmy joint, Figure 4 a cross section through the same along line 44 ofFigure 3. Figure 5 a' forming one of 4c the members of my joint. igure 6a top plan side elevation 'of a castin view of the castingand Figure 7 atop plan view of the assembled joint, a portion being shown in sectionto disclose the shape of the engagin surfaces. While ll have shown only45 the pre erred form of the invention ll wish to have it understoodthat various changes may be made within the scope of the claims heretoattached without departing from the spirit of the invention. a to Theframe member (1) of a motor vehicle terminates in a curved end (2)engaging the main spring (3). To this curved 811C118 secured by means ofa suitable clamp 4) the castin (6) the end surface (7) of w ich is easlight y curved-so as to rest snugly on the and its two sides (23)holding element (17 curved surface of the frame. The casting is providedwith two lateral projections (8) and (9), each of which is perforated asshown at (10) and (11) and the clamp (4) passes through these twoperforations to be secured by an suitable means as by the nuts (12). T eperforation (11) is elongated as shown in Figure 6, which adapts thecasting to be used for frames of different widths. From the castingextends rearwardly an arm (13) preferably cylindrical in shape as shownin Figure 5. This arm is disposed in spaced relation and parallel to thevertical central plane of the casting and'has a toothed or corrugatedinternal surface (14), the teeth or corrugations being arrangedradially. The body portion of the casting presents a curved rear surface(16) adapted to receive a cylindrical holding element ,(17) for thebracket (18).

The latter bracket is shown in Figure 1 as being substantiallytriangular in shape, its base (19) having the bumper rod (21) securedthereto by means of a clamp (22), and (24) instead of joining at theapex of the triangle terminating in arallel lips (26) adapted to beinserted into the cylindrical element (17 through'longitudinal slots(27) in its curved surface. The cylindrical element (17) is hollow, butthe side opposing the two slots (27) is made solid by the segment (28)which )rovides a sto for the lips (26).. One en d of the cylin or issolid as shown. at (29) and its surface is provided with radial teeth orcorrugations registering with the corrugations (14:) of the" castingandadapted to engage the same. At the opposite endof the holdin element1 provide a washer (31) and all t e elements, namely, the arm 0 thecasting,the solid and of the the li s of the bracket and the washer arefirmly eld together by. means of av bolt (32) penetrating registeringperforations in the said elements and the nut (33) threadedly engagingthe end i of the same.

To assemble the device the casting (6) is placed on the curvedsurface ofthe rame member and firmly secured thereto by means of a clamp (a andthe nuts (12). The lips of the brac ret may then be inserted into thecylindrical hol ing element (17) in the manner described, the solid endof the cylin der engaged with-thecorrugated surface of 1M) arm (6) ofthe casting, the washer inserted and all the elements combined into onesolid 'unit by means of the bolt (32) and the nut (33). It will. be seenthat due to this construction the base of the triangular bracket mayalways be maintained in a vertical position irrespective of the shape ofthe frame and the position of the bracket may be adjusted at any time bymerely loosening the nut (33) of the bolt (32). The casting is adaptedto 'fit on any frame member within reasonable limits due to theelongated perforation (11) and the cylinder can hold any size ofbrackets. If for instance brackets narrower than the length of theslots' were selected it would only be necessary to tighten the nut onthe bolt (32) so as to.

. force the washer (31) into firm contact in my copending application,

with the lips. v

The devlce is superior to that described (previously referred to, in itssimplicity an furthermore by the fact that it allows of a more readyengagement between the corrugated surfaces.

I claim: v o

1. An adjustable joint of the character described, comprising a castingterminatingin a flat arm, a cylinder having one solid end adapted toengage the flat arm and to support a bracket in its central portion andmeans for securing the cylinder to the, arm.

integer 2. An adjustable joint of the character described, comprising acasting terminating .in a fiat arm,-a cylinder having one solid endadapted to engage the flat arm and to support a bracket in its centralportion, a Washer at the other end adapted to bear on the bracket so asto hold the same, and

'a central bolt extending through the arm and to support a bracket inits central portion and means for securing the cylinder to the arm.

4. An adjustable jointof the character described, comprising a castingterminating in a flat arm presenting a circular surface with radialcorrugations therein, a cylinder having one solid end With registeringcorrugations adapted to engage said surface and to support a bracket inits central ortion, a Washer at the other end adapte to bear on thebracket so as to hold the same, and a central bolt extending through thearm and the cylinder for binding all the elements into one firm unit.
